RAILROAD SLEEPER AND CHAIR.

SPECIFICATION forming part 0! Letters Patent No. 344,185, dated June 22,1886.

Application filed April 13, 1886. Serial No. Iii- ,718.

To all whont it may concern:

Beit known that I, WORTH KILPATRIOK. a citizen of the United States ofAmerica, residing at Gonnellsville, in the county of Fayette and Stateof Pennsylvania. have invented a new and useful Railroad Sleeper andChair, of which the following is a specification.

My invention has relation to improvements in railroad sleepers orcrossties and chairs, and the objects are, first, to provide ametalliccross-tie or sleeper of a simple, durable, and effective construction;second. to provide chairs which are effective to hold the rails inposition and which set secure and firm in the cross-tie, and whichchairs may be conveniently adjusted to the desired position on thetrack; and, third, to simplify the construction of metallic cross-tiesand trackchairs.

With these objects in view my invention consists, first, in a metallicrailroad cross-tie of peculiar construction; second, in a railchair ofpeculiar construction to set on and be held by such cross-tie; and,third, in the novel construction and combination of the parts, as willbe hereinafter fully described, and specifically as pointed out in theclaims made hereto, as required by the statute.

I have fully illustrated my invention in the accompanying drawings,forming a part of this specification, wherein Figure]. is a longitudinalsection of the cross-tie with the chairs in position thereon and therails set in the chairs. Fig. 2 is a plan view of the cross-tie withchairs and rails set thereon. Fig. 3 is a transverse section of thecross-tie, taken on the line 00 as of'Fig. 2, wherein the chair withrail is also shown. Fig. 4 is a plan view of a section of the cross-tie,showing the notches through which the T-flange of the chair slips. Fig.5 is a view of the chair-blank,showing it in condition before formingthe complete chair. Fig. 6 is a perspective of the completed chair, andFig. 7 is a modified form of the cross-tie, shown in cross-section.

In the drawings like letters and numbers indicate similar parts, and,reference being had thereto, the letter A designates my improved sleeperor cross-tie. This consists of a metal shell or plate ofsemi-cylindrical or elliptical conformation in cross-section, as l, withthe horizontal edges bent inward and No model.)

down to a common plane, as at 2. so that flat upper surface is providedfor the chairs to rest on. The edges of the flanges do not touch but areleft separated, as shown, to form a slot or opening, 8, in which theneck of the T-flange sets while the T sets under the flanges of thesleeper and holds the chair in its seat. These crossties may be rolledinto shape, or they may be struck into the desired form from a plate ofiron or steel by any mechanism adapted to that purpose. I have shown thepreferred form in Fig. 3 of the drawings, wherein the flanges are shownas struck or formed square from the terminations of the curve with themetal re-enl'orced in the under line of intersection; but a simpler formis shown in the modification given in Fig. 7, wherein the flanges arebent over, leaving the line of union with the body rounded. It isapparent that the only ditlerence is in the shape of the corners of theflanges in their union with the body, the former giving a largerface-surface, the latter being elliptical. Theslot3, left between theedges of the flanges, may vary with the size of the cross-tie and thechair and rail to be supported. In the flanges near to the determinedseat of each chair are formed notches 4, to admit the branches of the Ton the chair, and at the proper place, where the chair is seated, isformed a bolt-hole, 5, to receive the bolt which passes through thechair and secures the parts together. It will be perceived that thenotches in the flanges may be dispensed with and the chairs slipped onfrom the ends of the rails; but this is not always convenient; hence Iprovide the notches to be taken in the branches of the T.

The letter B designates the chair-blank. This is composed of thechair-seat 6, formed with side ears, 7, arranged diagonally to eachother on the edges of the blank and having their inner or rail faces, a,formed to suit the shape of the bottom flange and neck of the rail,whatever shape these may be, the purpose being to have the faces of theside ears fit snugly and firmly to the side of the rail. These side earsare struck up vertically, forming walls, and are the clamps which pinchthe rails and hold them in position.

011 the ends of the blank is formed a T- shaped flange, 8, which isstruck square down and is intended to hold the chair to the crosstie.This it does by the branches of the T setting under the flanges of thecross-tie, with the flanges in the grooves thus formed. In the chair isa bolt-hole, 9, through which and the bolt-hole in the cross-tie, asstated, the fastening-bolt 10 passes, and then the bolt is secured by anut on the end, or it may be riveted, if so desired.

The chair is conveniently and readily set on the rail by turning itabout to let the rail between the ears and then bringing it square inplace.

It will be perceived that the shape of the cross-tie gives readyopportunity for tamping the foundation and putting in the ballast. Theform also serves as a cushion to the weight of the passing loads, andthe clamping-ears of the chairs in connection to the tie and rail makeatirm and secure fastening, preventing the rails from twisting orspreading.

It will be observed that the chairs may be conveniently utilized on thecommon wooden cross-tie by leaving the T off, when they may be appliedasstated and secured by the usual stated.

5. The combination of the cross-tie formed with inwardlyturned flanges,forming a flat surface, and arranged with a slot or opening betweenthem, with a chair formed with side ears on opposite edges of the blankand diagonally to each other, and struck upward at right angles to thebody, and a depending T- flange on the end of the chair to engage theflanges on the cross-tie, and a fastening-bolt let through the chair andthe flange of the tie, substantially as described.

6. The combination of the cross tie formed with a curved body andinwardly turned edge flanges having notches, as 4, the chair formed withside ears struck vertically .0 the plate of the chair and arranged onopposite sides thereof and diagonally to each other, and the dependingflange on the end of the chair, and a fastening-bolt let through thechair and flange of the crosstie, substantially as described.

In witness whereof I have hereunto set my hand in the presence of twoattesting witnesses.
